Answer:A. Beaker A is used as an experiment to determine how acid affects limestone. Beaker B is used as a second experiment to determine how acid of a higher concentration affects limestone compared to acid of a lower concentration. Beaker C is used as a control to ensure that the limestone does not simply lose volume over time. Beaker D is used as a control to ensure that the limestone does not dissolve in plain water with a neutral pH.
